Answer 2

This is the scalar or dot product of 2 vectors

just multiply the values in the order they appear in the vector

a simple example would be

< 1 , 2> . <2, -1> = <1*2, 2*-1> = < 2, -2>

Answer 3

Well the key is V * W
V is 2,2,-2 and w is -5,-2, 6
So multiply each one with the corresponding
2* -5 = -10
2 * -2 = -4
-2 * 6 = -12 so the answer is
-10,-4,-12

Answer 4

? do you know

Answer 5

U is -4,1
V is -1,6
Key is -2u + 4v
Let's take the first value of each variable

-2 * -4 + 4 * -1 = 8 -4 = 4
The second value is
-2 * 1 + 4 * 6 = -2 + 24 = 22
So the answer is
4,22

Answer 6

It's easy just follow the key

Answer 7

Depends on.the question.

Answer 8

could you help me graph a few equations maybe?? @Will.H
